Comment 6 for bug 427118

I can reproduce this on a normal daily-live, so it is not an exotic issue. With all the work that has been put into karmic to make quicker shutdowns, it is a pity this bug ruins it all. I see there is no reaction upstream, but has anyone some idea what can be the reason for this issue? Should we look into a workaround for Karmic already, or will an upstream fix be accepted even if it arrives after karmic freeze or release?
